CT Carotid Angio

A CT Carotid Angio is a quick, low-dose scan that maps the blood vessels in your neck. At Cadabams Diagnostics, we use the latest 128-slice CT to spot narrowing or clots before they trigger a stroke. The test is painless, takes under 10 minutes, and gives your doctor a crystal-clear 3-D roadmap of your carotid arteries.

Carotid angiography is an imaging test that shows how blood flows through the carotid arteries—two major vessels on each side of your neck that supply the brain.

• CT Carotid Angio combines X-rays and computer technology after a small contrast dye injection.
• It highlights blockages, bulges (aneurysms), or tears (dissections) in high-resolution detail.
• Unlike older catheter methods, this scan is non-invasive and needs no overnight stay.

During analysis, our radiologists measure:

• Degree of stenosis – % of vessel narrowing
• Plaque type – calcified vs. soft lipid-rich
• Arterial wall thickness (IMT)
• Blood flow velocity (derived from CT)
• Presence of ulceration or thrombus

1. Evaluate stroke or TIA cause.
2. Plan carotid stenting or endarterectomy.
3. Follow-up after surgery.
4. Screen high-risk but silent patients.
5. Assess trauma-related neck vessel injury.

You may be advised to book a CT Carotid Angio if you have:

• Sudden weakness or numbness on one side of the body (TIA symptoms).
• A bruit (whooshing sound) heard by your doctor through a stethoscope.
• High blood pressure, diabetes, or high cholesterol that raises stroke risk.
• A history of smoking or heart disease. Age is not a barrier; adults from 30 to 80+ years undergo the scan safely at Cadabams Diagnostics.

• Early detection of blockages before symptoms appear.
• Accurate planning for minimally invasive surgery.
• Peace of mind if results are normal.
• One-stop process: scan, report, and cardiologist consult on the same day at Cadabams Diagnostics.

• Carotid artery stenosis
• Carotid artery aneurysm
• Carotid artery dissection
• Vasculitis (artery inflammation)
• Fibromuscular dysplasia
• Atherosclerotic plaque ulceration
